Changing an image to 3:4 or 16:9 crops the subject: how do you plan a safe composition?
When conversion to 3:4 or 16:9 crops important content, mark required regions before choosing cropping, padding or canvas extension. A changed display ratio does not automatically recompose the original, and filling a container commonly crops edges.

When conversion to 3:4 or 16:9 crops important content, mark required regions before choosing cropping, padding or canvas extension. A changed display ratio does not automatically recompose the original, and filling a container commonly crops edges. Preview subjects and text at the final size; changing width and height numbers alone does not establish successful adaptation.
Mark the subject and text that must remain visible
This applies to incomplete faces in vertical crops, clipped titles and website cards differing from source files. Record original and target ratios and required objects. Distinguish cropping in the exported file from cropping by the page display rule, and fix the relevant stage instead of repeatedly regenerating an image without inspecting the container.
Separate cover-style cropping from complete display with padding
Inspect crop frames and page fitting rules to determine whether content is cropped to fill or displayed completely. Centering may be unsuitable for an off-center subject, so inspect focal placement. Edge text also faces platform overlays and container variations. Marking source-image boundaries cannot guarantee preservation in every target display ratio.
Recompose or extend the canvas for the target ratio
Compose on a target-ratio canvas first, using padding or controlled outpainting where appropriate without stretching the subject. Website displays can adjust object positioning or show the whole image, accepting padding as the design requires. Inspect edges and perspective after background extension; do not distort people to fill space. Reflow text on the final canvas.
Check safe edges inside the actual display container
Preview the final export and actual page container, keeping faces, products and text complete. Test narrow and wide containers and thumbnails for focal drift from centered cropping. Success requires preserved important content and the intended ratio, not merely target dimensions in metadata. Blur from enlargement and distorted subjects require separate correction.
This article generated no images and does not claim outpainting reconstructs real unseen content accurately. Platform safe areas and overlays vary, so confirm margins for the destination. The 3:4 and 16:9 ratios are common examples rather than universal standards. If source information is insufficient, padding or reshooting may be preferable to forced cropping.
